I say that unless you never go out and have no friends friends and no hobbies that's going to be a massive waste of time. You should let the other person know about your interest in some way and see if they are interested as well. if the best way to find someone is to do what you're saying there wouldn't be a reason for dating apps in the first place.

EDIT: I'm not even sure why you are calling me names when you could not even understand what I said. you used the same derogatory terms against someone else that disagreed with you. You come off as very insecure.
